V6 Water Pump Install
I "inherited" a 2007 Rav4 when I got married a few months ago. Water pump started to go last week. Wasn't leaking, bearing was starting to go and making awful sound. Car has 134,000 miles on it. Wife told me that the original water pump had crapped out a few years ago at 70,000. After searching around on this site about water pumps on the Rav4, I learned a couple of things. Apparently the water pumps on this year of Rav4 are crap and the water pumps are a bitch to replace. After reading numerous posts about how spendy it was to replace the water pump or how the engine "supposedly" has to come out, I decided to replace the pump myself.
I ended up getting a water pump from NAPA for $66. The pump came with a new gasket as well. Also picked up a Haynes manual for $20. The manual gave excellent step by step instructions on how to remove and replace the pump. Pretty much you have to remove the serpetine belt, pulley from tensionor, idler pulley, overflow tank, motor mount on that side (i supported the engine from below with a floor jack). The manual says to take off the crankshaft pulley, but I didn't. I made getting to a few bolts a pain, but not difficult to remove. I pulled the water pump out from the top. The A/C lines on that side of the engine make getting the motor mount and water pump and little difficult. I think had I taken the crankshaft pulley off, the pump may have dropped out the bottom. In any case, I was able to jack up the motor a little bit to make more to remove the pump.
All in all. This took me about 8 hours, but that includes running to NAPA a couples of times and a buddy dropping by to BS. I probably could do this in 4-5 if I have to do it again. If anybody has any questions about this, I'll be happy to answer them.
